Native American Type Necklace? Red Blue and Black

My local thrift shop posted some jewelry that is for sale. I am hoping to get there early to go check this out. Is this a craft piece or maybe authentic?

 

My opinion…..Definitely imitation

 

Thank you JewelryPicker.

 

I see no Native American jewelery in this picture. The one in the front looks like a good crafter made it, but it's more Kenyan than NA. The bezel-set one at about one o'clock might be worth checking out though, if cheap. Some of those are sterling from India.

 

Thank you Evelyb. I am not a jewelry expert so I don't really even look at it much.

 

The red blue and black one could be Zulu or other South African.
I see a mix of styles and origins, but none of them NA.

Tagging our South African member @Boland , can you verify the origin?

 

Thank you Any.
